Hemipilia simplex is a species of plant in the family Orchidaceae.

It is endemic to China, where it is found in Sichuan and Yunnan.

[2][3][1] Its flowers are yellow, sometimes with brown spots.

[3] The species was first described in 1940 by Tsin Tang and Fa Tsuan Wang, as Amitostigma simplex.

[4] A molecular phylogenetic study in 2014 found that species of Amitostigma, Neottianthe and Ponerorchis were mixed together in a single clade, making none of the three genera monophyletic as then circumscribed.
